Method for quickly producing read and/or write readiness of an apparatus for reading from and/or writing to an optical recording medium, and correspondingly configured apparatus

Abstract

In order to more quickly produce read and/or write readiness of an apparatus for reading from and/or writing to an optical recording medium, in particular a DVD-ROM disc, it is proposed to read or to detect identification features, such as, for example, the “BCA data area” which individually identifies the respective recording medium and, after identification of the respectively inserted optical recording medium, to check whether adjustment parameters for the write and/or read unit of the apparatus have already been stored beforehand for this optical recording medium in a storage device. If this is the case, the adjustment parameters can be read from the storage device and be used as start values for the adjustment of the write and/or read unit. On the other hand, if no adjustment parameters have been found for the identified recording medium in the storage device, a normal adjustment of the write and/or read unit is carried out, the resulting adjustment parameter values subsequently being stored in the storage device.

What is claimed, is:  
     
         1 . Method for quickly producing read or write readiness of an apparatus for reading from or writing to an optical recording medium, the recording medium ( 1 ) having identification information items which individually identify the respective recording medium, comprising the steps of: 
 a) detecting the identification information items of the recording medium ( 1 ) after the latter has been inserted into the apparatus, in order to identify the recording medium,    b) checking whether, for the identified recording medium ( 1 ), at least one adjustment parameter value for operation of the apparatus is stored in storage means ( 5 ,  8 ), and    c) reading of the adjustment parameter value from the storage means ( 5 ,  8 ), if the check made in step b) is positive, and adjusting the apparatus in accordance with the adjustment parameter value read, in order to be able to read from or write to a data area of the recording medium ( 1 ).    
     
     
         2 . Method according to  claim 1 , characterized in that in the case where the check made in step b) is negative, the apparatus is adjusted in order to be able to read from or write to a data area of the optical recording medium ( 1 ), and afterwards, for the identified recording medium ( 1 ), at least one adjustment parameter value corresponding to the adjusted state of the apparatus is stored in the storage means ( 5 ,  8 ).  
     
     
         3 . Method according to  claim 1 , characterized in that one of non-volatile memory ( 5 ) of the apparatus and file stored on a non-volatile data carrier ( 8 ) is used as storage means.

         5 . Method according to  claim 1 , characterized in that, in step a), a BCA data area of the optical recording medium ( 1 ) is read as identification information.  
     
     
         6 . Method according to  claim 3 , characterized in that, in step a), a BCA data area of the optical recording medium ( 1 ) is read as identification information.  
     
     
         7 . Apparatus for reading from or writing to an optical recording medium, 
 the recording medium ( 1 ) having identification information items which individually identify the respective recording medium,    the apparatus having detection means ( 2 ) for detecting the identification information items of a recording medium ( 1 ) that has been inserted into the apparatus,    the apparatus having control means ( 4 ) for identifying the recording medium ( 1 ) that has been inserted into the apparatus using the detected identification information items, and for checking whether, for the identified recording medium ( 1 ),    at least one adjustment parameter value for operation of the apparatus is stored in storage means ( 5 ,  8 ),    the control means ( 4 ) being configured in such a way that, in the case where, for the identified recording medium ( 1 ) an adjustment parameter value has been able to be identified in the storage means ( 5 ,  8 ), the said control means read the adjustment parameter value from the storage means ( 5 ,  8 ) and adjust write means or read means ( 2 ) of the apparatus in accordance with the adjustment parameter value read, in order to be able to read from or write to a data area of the recording medium ( 1 ) via the write or read means ( 2 ).    
     
     
         8 . Apparatus according to  claim 7 , characterized in that the detection means are formed by the write means or read means ( 2 ).  
     
     
         9 . Apparatus according to  claim 7 , characterized in that the control means ( 4 ) are configured in such a way that, in the case where, for the identified recording medium ( 1 ), it has not been possible to identify an adjustment parameter value in the storage means ( 5 ,  8 ), the said control means carry out an adjustment of the write means or read means ( 2 ) and, for the identified recording medium ( 1 ), store in the storage means ( 5 ,  8 ) at least one adjustment parameter value corresponding to the adjusted state of the write means or read means ( 2 ).
